Connector for thin cartridge

Abstract

A connector for a thin cartridge is related. The connector has a first wall which holds contact members, and a second wall of which at least a portion is connected to the first wall. Only the first wall is inserted into the frame of the cartridge. The printed circuit board mounted on the cartridge is housed between the first wall and the second wall. The contact members held by the first wall come in contact with the terminals of the thin cartridge as a result of inserting the first wall into the frame of the cartridge.

What is claimed is: 
     
       1. In a connector to be used for a thin cartridge in which a printed circuit board provided at the tip surface thereof with terminals arranged in a pattern is mounted in a frame of the cartridge, said frame being provided at the tip thereof with an opening, and in which a space communicating with said opening is formed above said terminals, said connector comprising:   a first wall adapted to be inserted into said space in said frame through said opening of said cartridge;   a second wall of which at least a portion is connected to said first wall, said second wall being adapted to be located outside of said frame as covering said printed circuit board together with said first wall when said first wall is inserted into said space;   contact members held by said first wall such that the contacts of said contact members are adapted to come in contact with said terminals as a result of inserting the first wall into the tip opening of the frame; and   positioning means for accurately positioning said contact members and said terminals with respect to said first wall and said frame of said cartridge.   
     
     
       2. A connector for a thin cartridge as set forth in claim 1, wherein the first wall and the second wall are provided between the lateral side ends thereof with a concave relief portion which may permit the lower wall of an edge frame of said cartridge surrounding the opening thereof to be fitted. 
     
     
       3. A connector for a thin cartridge as set forth in claim 1, wherein the first wall is adapted to be fitted into a concave relief portion formed in the lateral wall portion of the edge frame surrounding the opening of the cartridge. 
     
     
       4. A connector for a thin cartridge as set forth in claim 1, wherein the positioning means comprises follower members disposed on the first wall which are fitted to guides formed in the edge frame surrounding the opening of the cartridge. 
     
     
       5. A connector for a thin cartridge as set forth in claim 2, wherein the positioning means comprises follower members disposed on the first wall which are fitted to guides formed in the edge frame surrounding the opening of the cartridge. 
     
     
       6. A connector for a thin cartridge as set forth in claim 3, wherein the positioning means comprises follower members disposed on the first wall which are fitted to guides formed in the edge frame surrounding the opening of the cartridge. 
     
     
       7. A connector for a thin cartridge as set forth in claim 1, wherein the positioning means comprises a groove formed in the first wall which is fitted to a vertical rib disposed on the edge frame surrounding the opening of the cartridge. 
     
     
       8. A connector for a thin cartridge as set forth in claim 2, wherein the positioning means comprises a groove formed in the first wall which is fitted to a vertical rib disposed on the edge frame surrounding the opening of the cartridge. 
     
     
       9. A connector for a thin cartridge as set forth in claim 3, wherein the positioning means comprises a groove formed in the first wall which is fitted to a vertical rib disposed on the edge frame surrounding the opening of the cartridge. 
     
     
       10. In a connector to be used for a thin cartridge in which a printed circuit board provided at the tip surface thereof with terminals arranged in a pattern is mounted in a frame of the cartridge, said frame being provided at the tip thereof with an opening, and in which a space communicating with said opening is formed above said terminals, said connector comprising:   a first wall adapted to be inserted into said space in said frame through said opening of said cartridge;   a second wall of which at least a portion is connected to said first wall, said second wall being adapted to be located outside of said frame as covering said printed circuit board together with said first wall when said first wall is inserted into said space;   contact members held by said first wall such that the contacts of said contact members are adapted to come in contact with said terminals; and   positioning means for accurately positioning said contact members and said terminals with respect to said first wall and said frame of said cartridge, said positioning means comprises follower members disposed on the first wall which are fitted to guides formal in the edge frame surrounding the opening of the cartridge.   
     
     
       11. A connector for a thin cartridge as set forth in claim 1, wherein the first wall and the second wall are provided between the lateral side ends thereof with a concave relief portion which may permit the lower wall of an edge frame of said cartridge surrounding the opening thereof to be fitted. 
     
     
       12. A connector for a thin cartridge as set forth in claim 1, wherein the first wall is adapted to be fitted into a concave relief portion formed in the lateral wall portion of the edge frame surrounding the opening of the cartridge. 
     
     
       13. In a connector to be used for a thin cartridge in which a printed circuit board provided at the tip surface thereof with terminals arranged in a pattern is mounted in a frame of the cartridge, said frame being provided at the tip thereof with an opening, and in which a space communicating with said opening is formed above said terminals, said connector comprising:   a first wall adapted to be inserted into said space in said frame through said opening of said cartridge;   a second wall of which at least a portion is connected to said first wall, said second wall being adapted to be located outside of said frame as covering said printed circuit board together with said first wall when said first wall is inserted into said space;   contact members held by said first wall such that the contacts of said contact members are adapted to come in contact with said terminals; and   positioning means for accurately positioning said contact members and said terminals with respect to said first wall and said frame of said cartridge, said positioning means comprises a groove formed in the first wall which is fitted to a vertical rib disposed on the edge frame surrounding the opening of the cartridge.
